以下技術可用於多種無線存取技術，如分碼多工存取(code division multiple access；CDMA)、分頻多工存取(frequency division multiple access；FDMA)、分時多工存取(time division multiple access； TDMA)、正交分頻多工存取(orthogonal frequency division multiple access；OFDMA)及單載波分頻多工存取(single carrier frequency division multiple access；SC-FDMA)。CDMA可藉由諸如通用地面無線電存取(universal terrestrial radio access；UTRA)或CDMA2000之無線電技術來實施。TDMA可藉由諸如行動通訊全球系統(global system for mobile communications；GSM)/通用封包無線電服務(general packet radio service；GPRS)/GSM進化增強資料率(enhanced data rates for GSM evolution；EDGE)之無線電技術來實施。OFDMA可藉由諸如IEEE 802.11(Wi-Fi)、IEEE 802.16(WiMAX)、IEEE 802.20，及進化UTRA(evolved UTRA；E-UTRA)之無線電技術而實施。UTRA是通用行動電訊系統(universal mobile telecommunications system；UMTS)之一部分。第三代合作夥伴計劃長期進化(3rd generation partnership project long term evolution；3GPP LTE)是進化UMTS(evolved UMTS；E-UMTS)之一部分，該進化UMTS使用E-UTRA且在下行鏈路中採用OFDMA及在上行鏈路中採用SC-FDMA。LTE進階版(LTE-advanced；LTE-A)是3GPP LTE之進化版本。 The following techniques can be used in a variety of wireless access technologies, such as code division multiple access (CDMA), frequency division multiple access (FDMA), time division multiplex access (time division) Multiple access; TDMA), orthogonal frequency division multiple access (OFDMA), and single carrier frequency division multiple access (SC-FDMA). CDMA can be implemented by a radio technology such as universal terrestrial radio access (UTRA) or CDMA2000. TDMA can be implemented by radio technologies such as global system for mobile communications (GSM)/general packet radio service (GPRS)/enhanced data rates for GSM evolution (EDGE) To implement. OFDMA can be implemented by radio technologies such as IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, and evolved UTRA (evolved UTRA; E-UTRA). UTRA is part of the universal mobile telecommunications system (UMTS). The 3rd generation partnership project long term evolution (3GPP LTE) is part of the evolutionary UMTS (Evolved UMTS; E-UMTS), which uses E-UTRA and employs OFDMA in the downlink. SC-FDMA is employed in the uplink. The LTE Advanced Edition (LTE-Avanced; LTE-A) is an evolutionary version of 3GPP LTE.

為闡明描述，儘管以下實施例將基於3GPP LTE/LTE-A來進行描述，但應將理解，本發明之技術精神並非限定於3GPP LTE/LTE-A。此外，在下文中用於本發明之實施例之特定術語係提供以協助理解本發明，且在符合不背離本發明之技術精神的範圍的情況下可在該等特定術語中進行多種修改。 To clarify the description, although the following embodiments will be described based on 3GPP LTE/LTE-A, it should be understood that the technical spirit of the present invention is not limited to 3GPP LTE/LTE-A. In addition, the specific terms used in the following examples of the present invention are provided to assist the understanding of the present invention, and various modifications may be made in the specific terms without departing from the scope of the technical spirit of the present invention.

第2圖是使用者裝備與基於3GPP無線電存取網路標準之E-UTRAN之間的無線電介面協定的控制平面及使用者平面的結構圖。 控制平面意謂著控制訊息發射時所在的過道，其中該等控制訊息由使用者裝備及網路使用以管理撥叫。使用者平面意謂著發射應用層中產生之資料(例如語音資料或網際網路封包資料)所在的過道。 Figure 2 is a block diagram of the control plane and user plane of the radio interface protocol between the user equipment and the E-UTRAN based on the 3GPP radio access network standard. The control plane means the aisle in which the control message is transmitted, wherein the control messages are used by the user equipment and the network to manage the dialing. The user plane means the aisle where the data generated in the application layer (such as voice data or internet packet data) is transmitted.

作為第一層之實體層藉由使用實體通道而向上層提供資訊傳送服務。實體層經由傳輸通道連接至媒體存取控制(medium access control；MAC)層，其中該媒體存取控制層位於實體層上方。資料係經由傳輸通道在媒體存取控制層與實體層之間進行傳送。資料係經由實體通道在發射側之一個實體層與接收側之另一實體層之間進行傳送。實體通道使用時間及頻率作為無線電資源。更詳細而言，實體通道在下行鏈路中依據正交分頻多工存取(orthogonal frequency division multiple access；OFDMA)方案而調變，且在上行鏈路中依據單載波分頻多工存取(single carrier frequency division multiple access；SC-FDMA)方案而調變。 The physical layer as the first layer provides an information transfer service to the upper layer by using a physical channel. The physical layer is connected to a medium access control (MAC) layer via a transmission channel, wherein the medium access control layer is located above the physical layer. The data is transferred between the medium access control layer and the physical layer via a transmission channel. The data is transmitted between the physical layer on the transmitting side and the other physical layer on the receiving side via the physical channel. The physical channel uses time and frequency as radio resources. In more detail, the physical channel is modulated in the downlink according to an orthogonal frequency division multiple access (OFDMA) scheme, and in the uplink according to single carrier frequency division multiplexing access (single carrier frequency division multiple access; SC-FDMA) scheme is modulated.

第二層之媒體存取控制(medium access control；MAC)層經由邏輯通道向MAC層上方之無線電鏈路控制(radio link control；RLC)層提供服務。第二層之RLC層支援可靠的資料發射。RLC層可作為MAC層內部的功能區塊而得以實施。為了在具有窄頻寬之無線電介面內有效地使用諸如IPv4或IPv6之IP封包發射資料，第二層之封包資料聚合協定(packet data convergence protocol；PDCP)層執行標頭壓縮以減小不必要控制資訊的大小。 The second layer of the medium access control (MAC) layer provides services to the radio link control (RLC) layer above the MAC layer via logical channels. The second layer of the RLC layer supports reliable data transmission. The RLC layer can be implemented as a functional block inside the MAC layer. In order to efficiently use IP packets such as IPv4 or IPv6 to transmit data in a radio interface with narrow bandwidth, the second layer of packet data convergence protocol (PDCP) layer performs header compression to reduce unnecessary control.

在步驟S301中，使用者裝備在剛進入一單元或電源開啟時，使用者裝備執行初始單元搜尋，如與基地台同步。為此，使用者裝備藉由從基地台接收主要同步通道(primary synchronization channel；P-SCH)及次要同步通道(secondary synchronization channel；S-SCH)而與基地台同步，且獲取諸如單元標識符(ID)等等之資訊。之後，使用者裝備可藉由接收來自基地台之實體廣播通道(physical broadcast channel；PBCH)而在單元內獲取廣播資訊。同時，使用者裝備可藉由在初始單元搜尋步驟中接收下行鏈路參考信號(downlink reference signal；DL RS)而識別下行鏈路通道狀態。 In step S301, when the user equipment is just entering a unit or the power is turned on, the user equipment performs an initial unit search, such as synchronization with the base station. To this end, the user equipment synchronizes with the base station by receiving a primary synchronization channel (P-SCH) and a secondary synchronization channel (S-SCH) from the base station, and acquires, for example, a unit identifier. (ID) and other information. Thereafter, the user equipment can acquire broadcast information in the unit by receiving a physical broadcast channel (PBCH) from the base station. At the same time, the user equipment can identify the downlink channel status by receiving a downlink reference signal (DL RS) in the initial unit search step.

在步驟S302中，已完成初始單元搜尋之使用者裝備可依據實體下行鏈路控制通道(physical downlink control channel；PDCCH)及PDCCH中承載之資訊，藉由接收實體下行鏈路共享通道(physical downlink shared channel；PDSCH)而獲取更詳細之系統資訊。 In step S302, the user equipment that has completed the initial unit search may receive the physical downlink shared channel (physical downlink shared channel) according to the physical downlink control channel (PDCCH) and the information carried in the PDCCH. Channel; PDSCH) for more detailed system information.

之後，使用者裝備可執行諸如步驟S303至S306之隨機存取程序(random access procedure；RACH)以完成對基地台之存取。為此，使用者裝備可經由實體隨機存取通道(physical random access channel；PRACH)發射前文(步驟S303)，且可經由PDCCH及對應於PDCCH之PDSCH接收該前文之回應訊息(步驟S304)。在基於競爭之RACH的情況下，使用者裝備可執行競爭解決程序，如發射(步驟S305)額外的實體隨機存取通道(physical random access channel；PRACH)及接收(步驟S306)實體下行鏈路控制通道及對應於該實體下行鏈路控制通道之實體下行鏈路共享通道。 Thereafter, the user equipment can perform a random access procedure (RACH) such as steps S303 to S306 to complete access to the base station. To this end, the user equipment may transmit the preamble via a physical random access channel (PRACH) (step S303), and may receive the foregoing response message via the PDCCH and the PDSCH corresponding to the PDCCH (step S304). In the case of contention based RACH, the user equipment may perform a contention resolution procedure, such as transmitting (step S305) additional physical random access channel (PRACH) and receiving (step S306) physical downlink control. A channel and a physical downlink shared channel corresponding to the physical downlink control channel.

已執行前述步驟的使用者裝備可接收實體下行鏈路控制通道 (physical downlink control channel；PDCCH)/實體下行鏈路共享通道(physical downlink shared channel；PDSCH)(步驟S307)且發射實體上行鏈路共享通道(physical uplink shared channel；PUSCH)及實體上行鏈路控制通道(physical uplink control channel；PUCCH)(步驟S308)，以作為發射上行鏈路/下行鏈路信號之一般程序。自使用者裝備發射至基地台的控制資訊將被稱作上行鏈路控制資訊(uplink control information；UCI)。UCI包括混合自動重傳及請求認可/否定認可(Hybrid Automatic Repeat and reQuest Acknowledgement/Negative Acknowledgement；HARQ ACK/NACK)、排程請求(Scheduling Request；SR)、通道狀態資訊(Channel State Information；CSI)等等。 在本說明書中，HARQ ACK/NACK將被稱作HARQ-ACK或ACK/NACK(A/N)。HARQ-ACK包括肯定ACK(簡言之，被稱作ACK)、否定ACK(negative ACK；NACK)、DTX及NACK/DTX中之至少一者。CSI包括通道品質指示符(channel quality indicator；CQI)、預編碼矩陣指示符(Precoding Matrix Indicator；PMI)、秩指示符(rank indicator；RI)等等。儘管UCI一般經由PUCCH而發射，但在控制資訊及訊務資料將同時發射之情況下，UCI可能經由PUSCH發射。此外，使用者裝備可依據網路請求/命令而非週期性地經由PUSCH發射UCI。 The user equipment that has performed the foregoing steps can receive the physical downlink control channel (physical downlink shared channel; PDCCH)/physical downlink shared channel (PDSCH) (step S307) and transmitting physical uplink shared channel (PUSCH) and physical uplink control channel (physical uplink control channel; PUCCH) (step S308) as a general procedure for transmitting an uplink/downlink signal. The control information transmitted from the user equipment to the base station will be referred to as uplink control information (UCI). UCI includes Hybrid Automatic Repeat and reQuest Acknowledgement/Negative Acknowledgement (HARQ ACK/NACK), Scheduling Request (SR), Channel State Information (CSI), etc. Wait. In this specification, HARQ ACK/NACK will be referred to as HARQ-ACK or ACK/NACK (A/N). The HARQ-ACK includes at least one of a positive ACK (in short, referred to as ACK), a negative ACK (Negative ACK; NACK), DTX, and NACK/DTX. The CSI includes a channel quality indicator (CQI), a Precoding Matrix Indicator (PMI), a rank indicator (RI), and the like. Although UCI is typically transmitted via PUCCH, UCI may be transmitted via PUSCH in the event that control information and traffic data are simultaneously transmitted. In addition, the user equipment can transmit the UCI via the PUSCH in accordance with the network request/command rather than periodically.

第4圖是圖示用於LTE系統中之無線電訊框之結構的圖表。 Figure 4 is a diagram illustrating the structure of a radio frame for use in an LTE system.

參看第4圖，在蜂巢式OFDM無線電封包通訊系統中，上行鏈路/下行鏈路資料封包發射是在子訊框單元中執行的，其中一個子訊框由包括複數個OFDM符號之給定時間間隔而定義。3GPP LTE標準支援適用於分頻雙工(frequency division duplex；FDD)之1類無線電訊 框結構及適用於分時雙工(time division duplex；TDD)之2類無線電訊框結構。 Referring to FIG. 4, in a cellular OFDM radio packet communication system, uplink/downlink data packet transmission is performed in a subframe unit, wherein a subframe is given a given time by a plurality of OFDM symbols. Defined by interval. 3GPP LTE standard supports Class 1 radio for frequency division duplex (FDD) The frame structure and the two types of radio frame structures suitable for time division duplex (TDD).

第4(a)圖是圖示1類無線電訊框結構之圖表。下行鏈路無線電訊框包括10個子訊框，每一子訊框在一時域中包括兩個時槽。發射一個子訊框所需之時間將被稱作發射時間間隔(transmission time interval；TTI)。例如，一個子訊框可具有1ms之長度，而一個時槽可具有0.5ms之長度。一個時槽在時域中包括複數個OFDM符號且在一頻域中包括複數個資源區塊(resource block；RB)。由於3GPP LTE系統在下行鏈路中使用OFDM，因此OFDM符號表示一個符號間隔。 OFDM符號可被稱作SC-FDMA符號或符號間隔。作為資源分配單元之資源區塊(resource block RB)可在一個時槽中包括複數個連續次載波。 Figure 4(a) is a diagram illustrating the structure of a Class 1 radio frame. The downlink radio frame includes 10 subframes, and each subframe includes two slots in a time domain. The time required to transmit a subframe will be referred to as the transmission time interval (TTI). For example, a sub-frame can have a length of 1 ms, and a time slot can have a length of 0.5 ms. A time slot includes a plurality of OFDM symbols in the time domain and includes a plurality of resource blocks (RBs) in a frequency domain. Since the 3GPP LTE system uses OFDM in the downlink, the OFDM symbol represents one symbol interval. An OFDM symbol may be referred to as an SC-FDMA symbol or symbol interval. A resource block RB as a resource allocation unit may include a plurality of consecutive subcarriers in one time slot.

一個時槽中包括之OFDM符號數目可依據循環字首(cyclic prefix；CP)之配置而改變。CP之實例包括延伸CP及正規CP。例如，如若OFDM符號係由正規CP配置，則包括在一個時槽中之OFDM符號之數目可為7。如若OFDM符號係由延伸CP配置，則由於一個OFDM符號之長度增長，因此一個時槽中包括之OFDM符號之數目小於在正規CP情況下之OFDM符號數目。例如，在延伸CP之情況下，一個時槽中包括之OFDM符號之數目可為6。如若通道狀況不穩定，如使用者裝備以高速移動之情況，則延伸CP可用以降低符號間干擾。 The number of OFDM symbols included in a time slot may vary depending on the configuration of the cyclic prefix (CP). Examples of CPs include extended CPs and regular CPs. For example, if the OFDM symbol is configured by a regular CP, the number of OFDM symbols included in one time slot may be seven. If the OFDM symbol is configured by the extended CP, since the length of one OFDM symbol increases, the number of OFDM symbols included in one time slot is smaller than the number of OFDM symbols in the case of a normal CP. For example, in the case of extending the CP, the number of OFDM symbols included in one time slot may be six. If the channel condition is unstable, such as when the user equipment is moving at high speed, the extended CP can be used to reduce intersymbol interference.

如若使用正規CP，則由於一個時槽包括7個OFDM符號，因此一個子訊框包括14個OFDM符號。此時，每一子訊框之前三個最大OFDM符號可分配至實體下行鏈路控制通道(physical downlink control channel；PDCCH)，且其他OFDM符號可分配至實體下行鏈路共享通道(physical downlink shared channel；PDSCH)。 If a normal CP is used, since one time slot includes 7 OFDM symbols, one subframe includes 14 OFDM symbols. At this time, the three largest OFDM symbols in each subframe can be allocated to a physical downlink control channel (PDCCH), and other OFDM symbols can be allocated to a physical downlink shared channel (physical downlink shared channel). ;PDSCH).

第4(b)圖是圖示2類無線電訊框結構之圖表。2類無線電訊框包括兩個半訊框，每半個訊框包括四個通用子訊框及一專用子訊框，該等通用子訊框包括兩個時槽，且該專用子訊框包括下行鏈路引導頻時槽(downlink pilot time slot；DWPTS)、保護時段(guard period；GP)及上行鏈路引導頻時槽(uplink pilot time slot；UpPTS)。 Figure 4(b) is a diagram illustrating the structure of a Class 2 radio frame. The type 2 radio frame includes two half frames, each half frame includes four universal subframes and a dedicated subframe, the universal subframe includes two time slots, and the dedicated subframe includes Downlink pilot time slot (DWPTS), guard period (GP), and uplink pilot time slot (UpPTS).

在專用子訊框中，DwPTS用於在使用者裝備處進行初始單元搜尋、同步或通道估計。UpPTS用於在基地台進行之通道估計及使用者裝備之上行鏈路發射同步。換言之，DwPTS用於下行鏈路發射，而UpPTS用於上行鏈路發射。特定而言，UpPTS用於PRACH前文或SRS發射。此外，保護時段將移除在上行鏈路中由於下行鏈路信號在上行鏈路與下行鏈路之間的多路徑延遲而出現之干擾。 In the dedicated subframe, DwPTS is used for initial unit search, synchronization or channel estimation at the user equipment. The UpPTS is used for channel estimation at the base station and for uplink transmission synchronization of the user equipment. In other words, DwPTS is used for downlink transmission and UpPTS is used for uplink transmission. In particular, UpPTS is used for PRACH preamble or SRS transmission. In addition, the guard period will remove interference that occurs in the uplink due to the multipath delay between the uplink and downlink of the downlink signal.

專用子訊框之配置在當前的3GPP標準文獻中定義，如下方之表1中所圖示。表1圖示在以下各個情況中的DwPTS及UpPTS，且其他區域經配置用於保護時段。 The configuration of the dedicated subframes is defined in the current 3GPP standard documents, as illustrated in Table 1 below. Table 1 illustrates DwPTS and UpPTS in each of the following cases, and other areas are configured for the guard period.

同時，2類無線電訊框之結構如下方表2中所圖示，該訊框結構亦即TDD系統中之上行鏈路/下行鏈路配置(uplink/downlink configuration；UL/DL configuration)。 At the same time, the structure of the type 2 radio frame is as shown in Table 2 below, which is the uplink/downlink configuration (UL/DL configuration) in the TDD system.

在上述表2中，D意謂著下行鏈路子訊框，U意謂著上行鏈路子訊框，且S意謂著專用子訊框。此外，表2亦圖示每一系統之上行鏈路/下行鏈路子訊框配置中之下行鏈路至上行鏈路的交換時段。 In Table 2 above, D means a downlink subframe, U means an uplink subframe, and S means a dedicated subframe. In addition, Table 2 also illustrates the downlink to uplink switching period in the uplink/downlink subframe configuration for each system.

前述無線電訊框之結構僅以示例為目的，且可對無線電訊框中包括之子訊框數目、子訊框中包括之時槽數目，或時槽中包括之符號數目進行多種修改。 The structure of the aforementioned radio frame is for example only, and various modifications may be made to the number of sub-frames included in the radio frame, the number of slots included in the subframe, or the number of symbols included in the slot.

第5圖是圖示下行鏈路時槽之資源柵格的圖表。 Figure 5 is a diagram illustrating a resource grid for a downlink time slot.

參看第5圖，下行鏈路時槽在一時域中包括複數個OFDM符號，且在一頻域中包括複數個資源區塊。由於每一資源區塊包括次載 波，因此下行鏈路時槽在頻域內包括x個次載波。儘管第5圖圖示下行鏈路時槽包括7個OFDM符號且資源區塊包括12個次載波，但將理解，下行鏈路時槽及資源區塊並非限定於第5圖之實例。例如，下行鏈路時槽中包括之OFDM符號之數目可依據CP長度而改變。 Referring to FIG. 5, the downlink time slot includes a plurality of OFDM symbols in a time domain and includes a plurality of resource blocks in a frequency domain. Since each resource block includes the second load Wave, so the downlink time slot includes x secondary carriers in the frequency domain. Although FIG. 5 illustrates that the downlink slot includes 7 OFDM symbols and the resource block includes 12 subcarriers, it will be understood that the downlink slot and resource block are not limited to the example of FIG. For example, the number of OFDM symbols included in the downlink time slot may vary depending on the length of the CP.

資源柵格上之每一元件將被稱作資源元件(resource element；RE)。一個資源元件由一個OFDM符號指標及一個次載波指標指示。一個RB包括x數目個資源元件。下行鏈路時槽中包括之資源區塊數目依據單元中配置之下行鏈路發射頻寬而定。 Each element on the resource grid will be referred to as a resource element (RE). A resource element is indicated by an OFDM symbol indicator and a secondary carrier indicator. One RB includes x number of resource elements. The number of resource blocks included in the downlink time slot depends on the downlink transmission bandwidth configured in the cell.

第6圖是圖示下行鏈路子訊框之結構的圖表。 Figure 6 is a diagram illustrating the structure of a downlink subframe.

參看第6圖，位於子訊框之第一時槽的前部之最大三個(四個)OFDM符號對應於控制通道所分配至的控制區域。其他OFDM符號對應於實體下行鏈路共享通道(physical downlink shared channel；PDSCH)所分配至的資料區域。用於LTE系統中之下行鏈路控制通道之實例包括實體控制格式指示符通道(Physical Control Format Indicator Channel；PCFICH)、實體下行鏈路控制通道(physical downlink control channel；PDCCH)，及實體混合式ARQ指示符通道(Physical Hybrid ARQ Indicator Channel；PHICH)。PCFICH自子訊框之第一OFDM符號發射，且承載關於在子訊框內用於發射控制通道之OFDM符號的數目之資訊。PHICH承載回應於上行鏈路發射之混合自動重傳及請求認可/否定認可(Hybrid Automatic Repeat reQuest acknowledgement/negative-acknowledgement；HARQ ACK/NACK)信號。 Referring to Figure 6, the maximum three (four) OFDM symbols located at the front of the first time slot of the subframe correspond to the control region to which the control channel is assigned. The other OFDM symbols correspond to a data area to which a physical downlink shared channel (PDSCH) is allocated. Examples of the downlink control channel used in the LTE system include a Physical Control Format Indicator Channel (PCFICH), a physical downlink control channel (PDCCH), and an entity hybrid ARQ. Indicator Hybrid ARQ Indicator Channel (PHICH). The PCFICH transmits from the first OFDM symbol of the subframe and carries information about the number of OFDM symbols used to transmit the control channel within the subframe. The PHICH bearers a Hybrid Automatic Repeat reQuest acknowledgement/negative-acknowledgement (HARQ ACK/NACK) signal in response to an uplink transmission.

經由PDCCH發射之控制資訊將被稱作下行鏈路控制資訊(downlink control information；DCI)。DCI包括使用者裝備或使用者 裝備群組之資源分配資訊。例如，DCI包括上行鏈路/下行鏈路排程資訊、上行鏈路發射(Tx)功率控制命令，等等。 The control information transmitted via the PDCCH will be referred to as downlink control information (DCI). DCI includes user equipment or users Resource allocation information for the equipment group. For example, DCI includes uplink/downlink scheduling information, uplink transmission (Tx) power control commands, and the like.

PDCCH可包括下行鏈路共享通道(downlink shared channel；DL-SCH)之傳輸格式及資源分配資訊、上行鏈路共享通道(uplink shared channel； UL-SCH)之傳輸格式及資源分配資訊、傳呼通道(paging channel；PCH)上之傳呼資訊、DL-SCH上之系統資訊、上層控制訊息之資源分配資訊(如在PDSCH上發射之隨機存取回應)、隨機使用者裝備群組內的單個使用者裝備(user equipment；UE)之發射(Tx)功率控制命令組、發射(Tx)功率控制命令，及網際網路協定上的語音(voice over Internet protocol；VoIP)之活動指示資訊。複數個PDCCH可在控制區域之內發射。使用者裝備可監測複數個PDCCH。 PDCCH在一個或複數個連續控制通道元件(control channel element；CCE)聚合時發射。CCE是用以基於無線電通道狀態而向PDCCH提供編碼速率的邏輯分配單元。CCE對應於複數個資源元件群組(resource element group；REG)。PDCCH之格式及PDCCH之可用位元的數目依據CCE之數目而決定。基地台依據將被發射至使用者裝備之DCI而決定PDCCH格式，且基地台將循環冗餘檢查(cyclic redundancy check；CRC)附著於控制資訊。依據PDCCH用途或PDCCH之所有者而定，CRC利用識別符(例如無線電網路暫時識別符(radio network temporary identifier；RNTI))遮蔽。例如，如若PDCCH用於特定使用者裝備，則CRC可利用對應之使用者裝備的單元RNTI(cell-RNTI；C-RNTI)遮蔽。如若PDCCH用於傳呼訊息，則CRC可利用傳呼識別符(例如傳呼RNTI(paging-RNTI；P-RNTI))遮蔽。如若PDCCH用於系統資訊(更詳細而言，系統資訊塊(system information block； SIB))，則CRC可利用系統資訊RNTI(system information RNTI；SI-RNTI)遮蔽。如若PDCCH用於隨機存取回應，則CRC可利用隨機存取RNTI(random access RNTI；RA-RNTI)遮蔽。 The PDCCH may include a downlink shared channel (DL-SCH) transmission format and resource allocation information, an uplink shared channel (UL-SCH) transmission format, resource allocation information, and a paging channel ( Paging information on paging channel; PCH), system information on DL-SCH, resource allocation information of upper layer control messages (such as random access response transmitted on PDSCH), single user equipment in random user equipment group (user equipment; UE) transmission (Tx) power control command group, transmission (Tx) power control command, and voice over Internet protocol (VoIP) activity indication information. A plurality of PDCCHs may be transmitted within the control region. The user equipment can monitor a plurality of PDCCHs. The PDCCH is transmitted when one or more consecutive control channel elements (CCEs) are aggregated. The CCE is a logical allocation unit to provide a coding rate to the PDCCH based on the radio channel status. The CCE corresponds to a plurality of resource element groups (REGs). The format of the PDCCH and the number of available bits of the PDCCH are determined according to the number of CCEs. The base station determines the PDCCH format according to the DCI to be transmitted to the user equipment, and the base station attaches a cyclic redundancy check (CRC) to the control information. Depending on the PDCCH usage or the owner of the PDCCH, the CRC is masked with an identifier such as a radio network temporary identifier (RNTI). For example, if the PDCCH is used for a specific user equipment, the CRC may be masked by the unit RNTI (cell-RNTI; C-RNTI) of the corresponding user equipment. If the PDCCH is used for paging messages, the CRC may be masked by a paging identifier (eg, paging RNTI (Paging-RNTI)). If the PDCCH is used for system information (in more detail, the system information block; SIB)), the CRC can be masked using system information RNTI (SI-RNTI). If the PDCCH is used for a random access response, the CRC may be masked using a random access RNTI (RA-RNTI).

第7圖是圖示用於LTE系統中之上行鏈路子訊框結構之圖表。 Figure 7 is a diagram illustrating the structure of an uplink subframe for use in an LTE system.

參看第7圖，上行鏈路子訊框包括複數個時槽(例如兩個)。 每一時槽可包括複數個SC-FDMA符號，其中每一時槽中包括之SC-FDMA符號之數目依據循環字首(cyclic prefix；CP)長度而改變。 上行鏈路子訊框在頻域中被分為資料區域及控制區域。資料區域包括PUSCH，且用以發射諸如語音之資料信號。控制區域包括PUCCH，且用以發射上行鏈路控制資訊(uplink control information；UCI)。 PUCCH包括在頻軸上位於資料區域兩個末端之RB對，且在時槽邊界上執行跳躍。 Referring to Figure 7, the uplink subframe includes a plurality of time slots (e.g., two). Each time slot may include a plurality of SC-FDMA symbols, wherein the number of SC-FDMA symbols included in each time slot varies depending on the length of the cyclic prefix (CP). The uplink subframe is divided into a data area and a control area in the frequency domain. The data area includes a PUSCH and is used to transmit a data signal such as voice. The control region includes a PUCCH and is used to transmit uplink control information (UCI). The PUCCH includes RB pairs located at both ends of the data area on the frequency axis, and performs a jump on the time slot boundary.

PUCCH可用以發射以下控制資訊。 The PUCCH can be used to transmit the following control information.

-排程請求(Scheduling Request；SR)：是用以請求上行鏈路UL-SCH資源之資訊。SR藉由使用開關鍵控(on-off keying；OOK)系統而發射。 - Scheduling Request (SR): Information used to request uplink UL-SCH resources. The SR is transmitted by using an on-off keying (OOK) system.

- HARQ ACK/NACK：是對PDSCH上之下行鏈路資料封包的回應信號。該信號表示是否已成功接收下行鏈路資料封包。發射ACK/NACK 1位元以回應於單個下行鏈路代碼字(codeword；CW)，且發射ACK/NACK 2位元以回應於兩個下行鏈路代碼字。 - HARQ ACK/NACK: is a response signal to the downlink data packet on the PDSCH. This signal indicates whether the downlink data packet has been successfully received. An ACK/NACK 1 bit is transmitted in response to a single downlink codeword (CW), and an ACK/NACK 2 bit is transmitted in response to two downlink codewords.

- 通道狀態資訊(Channel State Information；CSI)：是下行鏈路通道上之反饋資訊。CSI包括通道品質指示符(channel quality indicator；CQI)，及多輸入多輸出(Multiple Input Multiple Output； MIMO)相關反饋資訊包括秩指示符(rank indicator；RI)、預編碼矩陣指示符(precoding matrix indicator；PMI)、預編碼類型指示符(precoding type indicator；PTI)等等。每一子訊框使用20個位元。 - Channel State Information (CSI): is the feedback information on the downlink channel. CSI includes channel quality indicator (CQI) and multiple input multiple output (Multiple Input Multiple Output; The MIMO) related feedback information includes a rank indicator (RI), a precoding matrix indicator (PMI), a precoding type indicator (PTI), and the like. Each subframe uses 20 bits.

可從使用者裝備發射以用於子訊框之上行鏈路控制資訊(uplink control information；UCI)之品質依據可用於控制資訊發射的SC-FDMA符號之數目而定。可用於控制資訊發射之SC-FDMA符號意謂著除用於子訊框之參考信號發射之SC-FDMA符號之外的剩餘SC-FDMA符號，且在子訊框設定有探測參考信號(sounding reference signal SRS)之情況下，該子訊框之最末SC-FDMA符號不包括在內。參考信號用於PUCCH之相干性偵測。 The quality of the uplink control information (UCI) that can be transmitted from the user equipment for the subframe is determined by the number of SC-FDMA symbols that can be used to control the information transmission. The SC-FDMA symbol that can be used to control information transmission means the remaining SC-FDMA symbols except for the SC-FDMA symbol used for the reference signal transmission of the subframe, and the sounding reference is set in the subframe. In the case of signal SRS), the last SC-FDMA symbol of the subframe is not included. The reference signal is used for coherence detection of PUCCH.

下文中對PUCCH揹負進行說明。 The PUCCH piggyback is explained below.

在舊有3GPP LTE系統(例如版本8)之上行鏈路發射情況下，維持具有影響功率放大器效能之優良的峰值平均功率比(peak-to-average power ratio；PAPR)或優良的立方度量(cubic metric；CM)之單載波發射，以有效地利用UE之功率放大器。特定而言，在舊有LTE系統之PUSCH發射情況下，意欲發射之資料的單載波特性藉由DFT預編碼而得以維持。在PUCCH發射之情況下，單載波特性可藉由以在一序列上載入資訊之方式發射該序列而得以維持，該序列具有該單載波特性。然而，在未連續地將DFT預編碼資料指定至頻軸的情況下，或在同時發射PUSCH及PUCCH的情況下，不維持單載波特性。 In the case of uplink transmissions of legacy 3GPP LTE systems (eg, Release 8), maintain excellent peak-to-average power ratio (PAPR) or excellent cubic metrics (cubic) that affect power amplifier performance (cubic) Single carrier transmission of metric; CM) to effectively utilize the power amplifier of the UE. In particular, in the case of PUSCH transmissions of legacy LTE systems, the single carrier characteristics of the data intended to be transmitted are maintained by DFT precoding. In the case of PUCCH transmission, the single carrier characteristic can be maintained by transmitting the sequence in such a manner that information is loaded in a sequence having the single carrier characteristic. However, in the case where DFT precoding data is not continuously assigned to the frequency axis, or in the case where PUSCH and PUCCH are simultaneously transmitted, the single carrier characteristic is not maintained.

由此，如第8圖中所繪示，在子訊框中存在與PUCCH發射相同之PUSCH發射的情況下，本應在PUCCH上發射之上行鏈路控制資訊(uplink control information；UCI)在PUSCH上與資料一起被發射(揹負)以維持單載波特性。 Thus, as shown in FIG. 8, in the case where there is the same PUSCH transmission as the PUCCH transmission in the subframe, the uplink control information (UCI) that should be transmitted on the PUCCH is on the PUSCH. The above is transmitted (backed up) along with the data to maintain single carrier characteristics.

如前述描述中所提及，由於PUCCH及PUSCH無法在舊有LTE UE中同時發射，因此在PUSCH所發射至之子訊框中，使用在PUSCH區域中對UCI(CQI/PMI、HARQ-ACK、RI，等等)進行多工之方法。例如，在經指定以發射PUSCH之子訊框中發射CQI及/或PMI的情況下，可藉由在DFT擴展之前對UL-SCH資料及CQI/PMI進行多工而將控制資訊及資料一起發射。在此情況下，UL-SCH資料在慮及CQI/PMI資源之情況下執行速率匹配。此外，可在PUSCH區域中以對UL-SCH資料進行刪餘之方式對諸如HARQ ACK、RI等等之控制資訊進行多工。 As mentioned in the foregoing description, since the PUCCH and the PUSCH cannot be simultaneously transmitted in the legacy LTE UE, UCI (CQI/PMI, HARQ-ACK, RI) is used in the PUSCH region in the subframe to which the PUSCH is transmitted. , etc.) The method of doing multiplex. For example, in the case of transmitting a CQI and/or PMI in a subframe designated to transmit a PUSCH, the control information and the data may be transmitted together by multiplexing the UL-SCH data and the CQI/PMI before the DFT extension. In this case, the UL-SCH data performs rate matching taking into account the CQI/PMI resources. In addition, control information such as HARQ ACK, RI, etc., may be multiplexed in the PUSCH region by puncturing the UL-SCH data.

第9圖是處理UL-SCH資料及控制資訊之實例圖表。 Figure 9 is an example diagram of processing UL-SCH data and control information.

參看第9圖，在UL-SCH上發射之資料在每一發射時間間隔(transmission time interval；TTI)中以傳輸區塊(transport block；TB)形式經傳遞至編碼單元。 Referring to Figure 9, the data transmitted on the UL-SCH is transmitted to the coding unit in the form of a transport block (TB) in each transmission time interval (TTI).

同位位元p ₀、p ₁、p ₂、p ₃、…、p _L-1附著於自上層傳送之傳輸區塊之位元a ₀、a ₁、a ₂、a ₃、…、a _A-1。在此情況下，傳輸區塊之大小對應於A及同位位元之數目對應於L=24。作為錯誤偵測碼，循環冗餘檢查(cyclic redundancy check；CRC)位元所附著於之輸入位元可表示為b ₀、b ₁、b ₂、b ₃、…、b _B-1。在此情況下，B指示包括CRC之傳輸區塊之位元數目[步驟S900]]]]。 The parity bits p ₀ , p ₁ , p ₂ , p ₃ , ..., p _{L -1 are} attached to the bits a ₀ , a ₁ , a ₂ , a ₃ , ..., a _{A -} of the transport block transmitted from the upper layer _{. 1} . In this case, the size of the transport block corresponds to the number of A and parity bits corresponding to L=24. As the error detection code, the input bit to which the cyclic redundancy check (CRC) bit is attached may be represented as b ₀ , b ₁ , b ₂ , b ₃ , ..., b _{B -1} . In this case, B indicates the number of bits including the transport block of the CRC [step S900]]].

b ₀、b ₁、b ₂、b ₃……b _B-1根據TB大小而分段至複數個代碼區塊(code block；CB)，且CRC附著於複數個分段CB。代碼區塊經分段及附著有CRC之位元對應於c _r0、c _r1、c _r2、c _r3……c _r(Kr-1)。在此情況下，r對應於代碼區塊(r=0……C-1)之數目，且Kr對應於根據代碼區塊r之位元之數目。此外，c指示代碼區塊之總數目[步驟S910]。 b ₀ , b ₁ , b ₂ , b ₃ ... b _{B -1} is segmented into a plurality of code blocks (CBs) according to the TB size, and the CRC is attached to the plurality of segments CB. The code block is segmented and the bit to which the CRC is attached corresponds to c _{r 0} , c _{r 1} , c _{r 2} , c _{r 3} ... c _{r ( Kr -1)} . In this case, r corresponds to the number of code blocks (r = 0 ... C-1), and Kr corresponds to the number of bits according to the code block r. Further, c indicates the total number of code blocks [step S910].

隨後，對輸入通道編碼單元之c _r0、c _r1、c _r2、c _r3、…、c _r(Kr-1)執行通道編碼步驟。在通道編碼之後，位元變為、、、、…、。在此情況下，i對應於編碼資料串流之指標(i=0、1，及2)，且Dr指示代碼區塊r中第i個編碼資料串流之位元數目(亦即D_r=K_r+4)。r指示代碼區塊數目(r=0、1、…、C-1)，且K_r指示代碼區塊r之位元之數目。此外，C指示代碼區塊之總數目。在本發明之實施例中，可藉由使用turbo編碼方案對每一代碼區塊執行通道編碼[步驟S920]。 Subsequently, a channel encoding step is performed on c _{r 0} , c _{r 1} , c _{r 2} , c _{r 3} , ..., c _{r ( Kr -1)} of the input channel coding unit. After the channel is encoded, the bit becomes , , , ,..., . In this case, i corresponds to the index of the encoded data stream (i=0, 1, and 2), and Dr indicates the number of bits of the i-th encoded data stream in the code block r (ie, D _r = K _r+ 4). r indicates the number of code blocks (r = 0, 1, ..., C-1), and K _r indicates the number of bits of the code block r. In addition, C indicates the total number of code blocks. In an embodiment of the present invention, channel coding may be performed on each code block by using a turbo coding scheme [step S920].

在執行通道編碼之後，執行速率匹配步驟。在速率匹配之後，位元對應於e _r0、e _r1、e _r2、e _r3、…、e _r(Er-1)。在此情況下，E_r指示第r個代碼區塊(其中r=0、1、…、C-1)中速率匹配位元之數目，且C指示代碼區塊之總數目[步驟S930]。 After performing channel coding, a rate matching step is performed. After rate matching, the bits correspond to e _{r 0} , e _{r 1} , e _{r 2} , e _{r 3} , ..., e _{r ( Er -1)} . In this case, E _r indicates the number of rate matching bits in the rth code block (where r = 0, 1, ..., C-1), and C indicates the total number of code blocks [step S930].

在速率匹配步驟之後執行代碼區塊串聯過程。在代碼區塊串聯之後，位元變為f ₀、f ₁、f ₂、f ₃、…、f _G-1。在此情況下，G指示編碼位元之總數目。然而，當以利用UL-SCH資料進行多工之方式發射控制資訊時，用於發射控制資訊之位元不包括在G中。f ₀、f ₁、f ₂、f ₃、…、f _G-1對應於UL-SCH代碼字[步驟S940]。 The code block concatenation process is performed after the rate matching step. After the code blocks are concatenated, the bits become f ₀ , f ₁ , f ₂ , f ₃ , ..., f _{G -1} . In this case, G indicates the total number of coded bits. However, when the control information is transmitted in a manner of multiplexing using the UL-SCH data, the bit used to transmit the control information is not included in the G. f ₀ , f ₁ , f ₂ , f ₃ , ..., f _{G -1} correspond to the UL-SCH code word [step S940].

在通道品質資訊(CQI及/或PQI)、RI及HARQ-ACK之情況下，通道編碼是獨立執行的[步驟S950、S960及S970]。基於每一控制資訊之編碼符號之數目而執行每一UCI之通道編碼。例如，編碼符號之數目可用以為編碼控制資訊執行速率匹配。編碼符號之數目對應於以下過程中之調變符號數目、RE數目，等等。 In the case of channel quality information (CQI and/or PQI), RI, and HARQ-ACK, channel coding is performed independently [steps S950, S960, and S970]. The channel coding of each UCI is performed based on the number of coded symbols for each control information. For example, the number of encoded symbols can be used to perform rate matching for encoding control information. The number of coded symbols corresponds to the number of modulation symbols, the number of REs, and the like in the following process.

藉由使用輸入位元序列o ₀、o ₁、o ₂、…、o _O-1而執行通道品質資訊(channel quality information；CQI)之通道編碼[步驟S950]。用 於通道品質資訊之通道編碼的輸出位元序列變為q ₀、q ₁、q ₂、q ₃、…、q _QCQI-1。待應用之通道編碼方案根據通道品質資訊之位元數目而有所不同。如若通道品質資訊之位元數目等於或大於11個位元，則附著CRC8位元。Q_CQI指示用於CQI之編碼位元之總數目。為了使位元序列長度匹配Q_CQI，可對編碼通道品質資訊執行速率匹配。此舉可表示為Q_CQI=Q’_CQI*Q_m。在此情況下，Q’_CQI對應於CQI之編碼符號數目，且Q_m對應於調變次序。Q_m及UL-SCH資料經相同配置。 Channel coding of channel quality information (CQI) is performed by using the input bit sequence o ₀ , o ₁ , o ₂ , ..., o _{O -1} [step S950]. The output bit sequence for channel coding for channel quality information becomes q ₀ , q ₁ , q ₂ , q ₃ , ..., q _{QCQI -1} . The channel coding scheme to be applied varies depending on the number of bits of the channel quality information. If the number of bits of the channel quality information is equal to or greater than 11 bits, the CRC8 bit is attached. The Q _CQI indicates the total number of coded bits used for the CQI. In order to match the bit sequence length to Q _CQI , rate matching can be performed on the encoded channel quality information. This can be expressed as Q _CQI = Q' _CQI * Q _m . In this case, Q _'CQI corresponding to the number of CQI coded symbols, and Q _m corresponding to the modulation order. The Q _m and UL-SCH data are configured identically.

藉由使用輸入位元序列或而執行RI之通道編碼。及分別指示1位元RI及2位元RI。 By using an input bit sequence or The channel code of the RI is executed. and One bit RI and two bit RI are indicated respectively.

在1位元RI之情況下，使用重複編碼。在2位元RI之情況下，使用(3,2)單工碼以用於編碼，且可循環及重複編碼資料。在RI等於或大於3個位元或RI等於或小於11個位元之情況下，藉由使用上行鏈路共享通道所使用之(32,0)RM碼對RI進行編碼。在RI等於或大於12個位元之情況下，藉由使用雙工RM結構將RI資訊分成兩個群組，且藉由使用(32,0)RM碼對每一群組進行編碼。藉由編碼RI區塊之組合而獲得輸出位元序列、、、…、。在此情況下，Q_RI指示用於RI之編碼位元之總數目。為了使編碼RI之長度匹配Q_RI，最終合併之編碼RI區塊可對應於部分區塊(亦即速率匹配)。此舉可表示為Q_RI=Q’_RI*Q_m。在此情況下，Q’_RI對應於RI之編碼符號數目，且Q_m對應於調變次序。Q_m及UL-SCH資料經相同配置。 In the case of a 1-bit RI, repeated coding is used. In the case of a 2-bit RI, a (3, 2) simplex code is used for encoding, and the encoded data can be cycled and repeated. In the case where RI is equal to or greater than 3 bits or RI is equal to or less than 11 bits, the RI is encoded by using the (32, 0) RM code used by the uplink shared channel. In the case where the RI is equal to or greater than 12 bits, the RI information is divided into two groups by using the duplex RM structure, and each group is encoded by using the (32, 0) RM code. Obtaining an output bit sequence by encoding a combination of RI blocks , , ,..., . In this case, Q _RI indicates the total number of coded bits for the RI. In order to match the length of the coded RI to Q _RI , the finally combined coded RI block may correspond to a partial block (ie, rate matching). This can be expressed as Q _RI =Q' _RI *Q _m . In this case, Q _'RI RI corresponding to the number of coded symbols, and Q _m corresponding to the modulation order. The Q _m and UL-SCH data are configured identically.

藉由使用步驟S970之輸入位元序列、或而執行HARQ-ACK之通道編碼。及分別指示1位元HARQ-ACK及2位元HARQ-ACK。此外，指示由具有兩個或兩個以上位元(亦即O ^ACK >2) 的資訊組成之HARQ-ACK。 By using the input bit sequence of step S970 , or The channel coding of HARQ-ACK is performed. and One bit HARQ-ACK and two bit HARQ-ACK are indicated, respectively. In addition, Indicates a HARQ-ACK consisting of information having two or more bits (ie, O ^ACK >2).

在此情況下，ACK藉由1編碼，且NACK藉由0編碼。在1位元HARQ-ACK之情況下，使用重複編碼。在2位元HARQ-ACK之情況下，(3,2)單工碼用於編碼，且可循環及重複編碼資料。在HARQ-ACK等於或大於3個位元或HARQ-ACK等於或小於11個位元之情況下，藉由使用上行鏈路共享通道所使用之(32,0)RM碼對HARQ-ACK進行編碼。在HARQ-ACK等於或大於12個位元之情況下，藉由使用雙工RM結構將HARQ-ACK資訊分成兩個群組，且藉由使用(32,0)RM碼對每一群組進行編碼。藉由編碼HARQ-ACK區塊之組合而獲得位元序列、、、…、。為了使位元序列之長度匹配Q_ACK，最終合併之編碼HARQ-ACK區塊可對應於部分區塊(亦即速率匹配)。此舉可表示為Q_ACK=Q’_ACK*Q_m。在此情況下，Q’_ACK對應於HARQ-ACK之編碼符號數目，且Q_m對應於調變次序。 Q_m及UL-SCH資料經相同配置。 In this case, the ACK is encoded by 1 and the NACK is encoded by 0. In the case of a 1-bit HARQ-ACK, repeated coding is used. In the case of a 2-bit HARQ-ACK, a (3, 2) simplex code is used for encoding, and the encoded data can be cycled and repeated. In the case where the HARQ-ACK is equal to or greater than 3 bits or the HARQ-ACK is equal to or less than 11 bits, the HARQ-ACK is encoded by using the (32, 0) RM code used by the uplink shared channel. . In the case where the HARQ-ACK is equal to or greater than 12 bits, the HARQ-ACK information is divided into two groups by using the duplex RM structure, and each group is performed by using the (32, 0) RM code. coding. Obtaining a bit sequence by encoding a combination of HARQ-ACK blocks , , ,..., . In order for the length of the bit sequence to match Q _ACK , the finally combined coded HARQ-ACK block may correspond to a partial block (ie, rate matching). This can be expressed as Q _ACK =Q' _ACK *Q _m . In this case, Q _'ACK corresponding to the number of HARQ-ACK coded symbols, and Q _m corresponding to the modulation order. The Q _m and UL-SCH data are configured identically.

資料/控制多工區塊之輸入對應於指示編碼US-SCH位元之f ₀、f ₁、f ₂、f ₃、…、f _G-1及指示編碼CQI/PMI位元之q ₀、q ₁、q ₂、q ₃、…、q _QCQI-1[步驟S980]。資料/控制多工區塊之輸出對應於g ₀、g ₁、g ₂、g ₃、…、g _H'-1。在此情況下，g _i對應於長度Qm(i=0、…、H'-1)之列向量。在此情況下，g _i (i=0、…、H’-1)指示長度(Q _m ˙N _L )之列向量。 此舉可表示為H=(G+N _L ˙Q _CQI )及H'=H/(N _L ˙Q _m )。在此情況下，N_L指示UL-SCH傳輸區塊所映射至之層的數目，且H指示分配至N_L數目個層之編碼位元之總數目，傳輸區塊針對UL-SCH資料及CQI/PMI資訊而經映射至該N_L數目個層。在此情況下，H對應於為UL-SCH資料及CQI/PMI分配之編碼位元之總數目。 The input of the data/control multiplex block corresponds to f ₀ , f ₁ , f ₂ , f ₃ , ..., f _{G -1} indicating the encoded US-SCH bit and q ₀ , q indicating the encoded CQI/PMI bit. ₁ , q ₂ , q ₃ , ..., q _{QCQI -1} [Step S980]. The output of the data/control multiplex block corresponds to g ₀ , g ₁ , g ₂ , g ₃ , ..., g _{H '-1} . In this case, g _i corresponds to a column vector of length Qm (i = 0, ..., H'-1). In this case, g _i ( i =0, ..., H' -1) indicates a column vector of length ( Q _m ̇ N _L ). This can be expressed as H = ( G + N _L ̇ Q _CQI ) and H' = H / ( N _L ̇ Q _m ). In this case, N _L indicates the number of layers to which the UL-SCH transport block is mapped, and H indicates the total number of coded bits allocated to the number of N _L layers, which are for UL-SCH data and CQI /PMI information is mapped to the number of layers of the N _L . In this case, H corresponds to the total number of coded bits allocated for UL-SCH data and CQI/PMI.

在通道交錯器中針對輸入通道交錯器中之編碼位元執行通道交錯步驟。在此情況下，通道交錯器之輸入對應於資料/控制多工區塊之輸出g ₀、g ₁、g ₂、g ₃、…、g _H'-₁、編碼秩指示符、、、…、，及編碼HARQ-ACK 、、、…、[步驟S990]。 A channel interleaving step is performed in the channel interleaver for the coding bits in the input channel interleaver. In this case, the input of the channel interleaver corresponds to the output of the data/control multiplex block g ₀ , g ₁ , g ₂ , g ₃ , ..., g _{H '} - ₁ , the coding rank indicator , , ,..., And encoding HARQ-ACK , , ,..., [Step S990].

在步驟S990中，g _i 對應於CQI/PMI之Q_m長度之列向量(其中i=0、…、H’-1，H’=H/Q_m)。對應於ACK/NACK之Q_m長度之列向量(其中i=0、…、Q'_ACK-1，Q’_ACK=Q_ACK/Q_m)。對應於RI之Q_m長度之列向量(其中i=0、…、Q'_RI-1，Q’_RI=Q_RI/Q_m)。 In step S990, g _i corresponds to a column vector of Q _m lengths of CQI/PMI (where i=0, . . . , H′-1, H′=H/Q _m ). A column vector corresponding to the Q _m length of ACK/NACK (where i=0, . . . , Q′ _ACK− 1, Q′ _ACK =Q _ACK /Q _m ). A column vector corresponding to the Q _m length of RI (where i = 0, ..., Q' _{RI -} 1, Q' _RI = Q _RI / Q _m ).

通道交錯器對用以發射PUSCH之控制資訊及/或UL-SCH資料進行多工。具體而言，通道交錯器包括將控制資訊及UL-SCH資料映射至對應於PUSCH資源之通道交錯器矩陣之過程。 The channel interleaver performs multiplexing on control information and/or UL-SCH data used to transmit the PUSCH. In particular, the channel interleaver includes a process of mapping control information and UL-SCH data to a channel interleaver matrix corresponding to PUSCH resources.

在執行通道交錯之後，自通道交錯器矩陣逐列輸出位元序列h ₀、h ₁、h ₂、…、h _H+QRI-1。輸出之位元序列映射至資源柵格。 After performing channel interleaving, the bit sequence h ₀ , h ₁ , h ₂ , ..., h _{H + QRI -1} is output column by column from the channel interleaver matrix. The output bit sequence is mapped to the resource grid.

第10圖是在PUSCH上對上行鏈路控制資訊及UL-SCH資料進行多工之方法的實例之圖表。 Figure 10 is a diagram showing an example of a method of multiplexing uplink control information and UL-SCH data on a PUSCH.

當使用者裝備(user equipment；UE)意欲在分配有PUSCH發射之子訊框中發射控制資訊時，UE對上行鏈路控制資訊(uplink control information；UCI)及UL-SCH資料同時進行多工，然後再執行DFT擴展。上行鏈路控制資訊(uplink control information；UCI)包括選自由以下各者組成之群組中之至少一者：CQI/PMI、HARQ-ACK/NACK及RI。 When the user equipment (UE) intends to transmit control information in the subframe in which the PUSCH transmission is allocated, the UE simultaneously performs multiplex processing on the uplink control information (UCI) and the UL-SCH data, and then Then perform DFT extension. The uplink control information (UCI) includes at least one selected from the group consisting of CQI/PMI, HARQ-ACK/NACK, and RI.

用於發射CQI/PMI、ACK/NACK及RI之RE之每一數目是基於調變及編碼方案(modulation and coding scheme；MCS)及分配用以發射PUSCH之偏移值(、、)而決定的。偏移值 允許編碼速率根據控制資訊而彼此不同，且由上層(例如RRC層)信號半靜態配置偏移值。UL-SCH資料及控制資訊並非映射至相同RE。 控制資訊以同時存在於子訊框之兩個時槽中之方式經映射。由於基地台能夠提前知曉控制資訊將在PUSCH上發射，因此基地台可易於對控制資訊及資料封包解多工。 Each number of REs used to transmit CQI/PMI, ACK/NACK, and RI is based on a modulation and coding scheme (MCS) and an offset value assigned to transmit PUSCH ( , , ) decided. The offset values allow the encoding rates to differ from each other according to the control information, and the offset values are semi-statically configured by the upper layer (eg, RRC layer) signal. UL-SCH data and control information are not mapped to the same RE. The control information is mapped in such a way that it exists in both time slots of the subframe. Since the base station can know in advance that the control information will be transmitted on the PUSCH, the base station can easily demultiplex the control information and data packets.

參看第10圖，CQI及/或PMI(CQI/PMI)資源位於UL-SCH資料來源之起始點，且順序地映射至單個次載波上之全部SC-FDMA符號，且映射是在下一次載波上執行的。CQI/PMI在次載波中自左側映射至右側，亦即在SC-FDMA符號指標增大之方向上映射。速率匹配是在慮及CQI/PMI資源之量(亦即編碼符號數目)的情況下，針對PUSCH資料(UL-SCH資料)執行的。CQI/PMI使用與UL-SCH資料相同之調變次序。 Referring to Figure 10, the CQI and/or PMI (CQI/PMI) resources are located at the starting point of the UL-SCH data source and are sequentially mapped to all SC-FDMA symbols on a single secondary carrier, and the mapping is on the next carrier. implemented. The CQI/PMI is mapped from the left side to the right side in the secondary carrier, that is, in the direction in which the SC-FDMA symbol index is increased. Rate matching is performed for PUSCH data (UL-SCH data) taking into account the amount of CQI/PMI resources (i.e., the number of coded symbols). The CQI/PMI uses the same modulation order as the UL-SCH data.

例如，如若CQI/PMI資訊大小(有效負荷大小)較小(例如等於或小於11個位元)，則與PUCCH資料發射類似，CQI/PMI資訊使用(32,k)區塊碼，且可重複編碼資料。如若CQI/PMI資訊大小較小，則不使用CRC。 For example, if the CQI/PMI information size (payload size) is small (for example, equal to or less than 11 bits), similar to PUCCH data transmission, CQI/PMI information uses (32, k) block code and can be repeated. Coding data. If the CQI/PMI information size is small, the CRC is not used.

如若CQI/PMI資訊大小較大(例如大於11個位元)，則附有8位元CRC，且使用咬尾卷積碼執行通道編碼及速率匹配。將ACK/NACK***SC-FDMA資源之一部分中，UL-SCH資料藉由刪餘而映射至該部分中。ACK/NACK定位在RS側處及自底部至頂部***對應之SC-FDMA符號中，亦即以次載波指標增大之方向***。 If the CQI/PMI information size is large (for example, greater than 11 bits), an 8-bit CRC is attached, and channel coding and rate matching are performed using the tail biting convolutional code. The ACK/NACK is inserted into one of the SC-FDMA resources, and the UL-SCH data is mapped into the portion by puncturing. The ACK/NACK is located at the RS side and inserted into the corresponding SC-FDMA symbol from the bottom to the top, that is, inserted in the direction in which the subcarrier index is increased.

在正規CP之情況下，如第10圖所示，用於ACK/NACK之SC-FDMA符號定位在每一時槽中之SC-FDMA符號#2及#4處。編碼RI定位在符號ACK/NACK側(亦即符號#1及#5)，無論是否在子訊 框中實際發射ACK/NACK。在此情況下，ACK/NACK、RI及CQI/PMI經獨立編碼。 In the case of a normal CP, as shown in Fig. 10, SC-FDMA symbols for ACK/NACK are located at SC-FDMA symbols #2 and #4 in each time slot. The coded RI is located on the symbol ACK/NACK side (ie, symbols #1 and #5), whether or not it is in the sub-information. The frame actually transmits ACK/NACK. In this case, ACK/NACK, RI, and CQI/PMI are independently encoded.

第11圖是載波聚合(carrier aggregation；CA)通訊系統之一實例之圖表。 Figure 11 is a diagram of an example of a carrier aggregation (CA) communication system.

參看第11圖，可以聚合複數個UL/DL分量載波(component carrier；CC)之方式支援更寬之UL/DL頻寬。術語「分量載波」可由如載波、單元等等之同等術語替代。每一分量載波可在頻域中鄰近於彼此或不鄰近於彼此。可單獨決定每一分量載波之頻寬。不對稱之載波聚合亦有可能，該載波聚合意謂著下行鏈路分量載波(downlink component carrier；DL CC)之數目與上行鏈路分量載波(uplink component carrier；UL CC)之數目互不相同。同時，控制資訊可經設定以僅在特定CC上收發。特定CC被稱作主要CC，而其餘CC可被稱作次級CC。 Referring to Fig. 11, a wider UL/DL bandwidth can be supported by aggregating a plurality of UL/DL component carriers (CCs). The term "component carrier" can be replaced by equivalent terms such as carrier, unit, and the like. Each component carrier may be adjacent to each other or not adjacent to each other in the frequency domain. The bandwidth of each component carrier can be determined individually. Asymmetric carrier aggregation is also possible. The carrier aggregation means that the number of downlink component carriers (DL CCs) and the number of uplink component carriers (UL CCs) are different from each other. At the same time, the control information can be set to be sent and received only on a specific CC. A specific CC is referred to as a primary CC, and the remaining CCs may be referred to as secondary CCs.

如一個實例所示，在應用交叉載波排程(或交叉CC排程)之情況下，在DL CC #0上發射用於進行DL分配之PDCCH，且對應之PDSCH可在DL CC #2上發射。對於交叉CC排程而言，可考慮引入載波指示符欄位(carrier indicator field；CIF)。CIF是否存在於PDCCH內部可經由上層傳訊(例如RRC傳訊)以半靜態及特定於使用者(或特定於使用者群組)之方式而經配置。PDCCH發射之基本要素可概述如下。 As shown in one example, in the case of applying cross-carrier scheduling (or cross-CC scheduling), a PDCCH for DL allocation is transmitted on DL CC #0, and the corresponding PDSCH can be transmitted on DL CC #2. . For cross-CC scheduling, consider introducing a carrier indicator field (CIF). Whether the CIF exists inside the PDCCH can be configured in a semi-static and user-specific (or user-specific group) manner via upper layer communication (eg, RRC communication). The basic elements of PDCCH transmission can be summarized as follows.

■CIF已去能：DL CC上之PDCCH在相同DL CC上分配PDSCH資源或在單鏈接UL CC上分配PUSCH資源。 ■ CIF has been de-energized: The PDCCH on the DL CC allocates PDSCH resources on the same DL CC or allocates PUSCH resources on a single-link UL CC.

●無CIF ●No CIF

●與LTE PDCCH結構(相同的編碼、相同的基於CCE之資源映射)及DCI格式相同 ● Same as LTE PDCCH structure (same coding, same CCE-based resource mapping) and DCI format

■CIF已賦能：DL CC上之PDCCH在複數個聚合DL/UL CC中之特定DL/UL CC上使用CIF來分配PDSCH或PUSCH資源。 ■ CIF is enabled: The PDCCH on the DL CC uses CIF to allocate PDSCH or PUSCH resources on a specific DL/UL CC in a plurality of aggregated DL/UL CCs.

●包括CIF之擴展LTE DCI格式 ●Extended LTE DCI format including CIF

- CIF(若配置)是固定x位元欄(例如x=3) - CIF (if configured) is a fixed x bit field (eg x=3)

-無論DCI格式大小如何，CIF(若配置)之位置是固定的 - Regardless of the size of the DCI format, the location of the CIF (if configured) is fixed

●LTE PDCCH結構(相同的編碼、相同的基於CCE之資源映射)之再使用 ● Reuse of LTE PDCCH structure (same coding, same CCE-based resource mapping)

在CIF存在於PDCCH內部之情況下，基地台能夠分配PDCCH監測之DL CC集，以降低使用者裝備側之BD複雜度。PDCCH監測之DL CC集為經聚合之整體DL CC中之一部分，且包括至少一個DL CC。使用者裝備可僅能夠在對應DL CC上執行PDCCH之偵測/解碼。特定而言，對於PDSCH/PUSCH之排程，基地台可僅能夠在PDCCH監測之DL CC上發射PDCCH。PDCCH監測之DL CC集可特定於UE、特定於UE群組或特定於單元而配置。術語「PDCCH監測之DL CC」可由同等術語替代，該術語如監測載波、監測單元等等。此外，經聚合以用於使用者裝備之CC可由同等術語替代，該術語如服務CC、服務載波、服務單元，等等。 In the case where the CIF exists inside the PDCCH, the base station can allocate the DL CC set of the PDCCH monitoring to reduce the BD complexity of the user equipment side. The DL CC set monitored by the PDCCH is part of the aggregated overall DL CC and includes at least one DL CC. The user equipment can only perform PDCCH detection/decoding on the corresponding DL CC. In particular, for scheduling of PDSCH/PUSCH, the base station may only be able to transmit the PDCCH on the DL CC monitored by the PDCCH. The DL CC set monitored by the PDCCH may be UE-specific, UE-specific, or cell-specific. The term "DL CC for PDCCH monitoring" may be replaced by an equivalent term such as a monitoring carrier, a monitoring unit, and the like. Moreover, CCs that are aggregated for use in user equipment may be replaced by equivalent terms such as a serving CC, a service carrier, a service unit, and the like.

第12圖是在複數個載波彼此聚合之情況下的排程實例之圖表。假設3個DL CC聚合，且DL CC A經配置為PDCCH監測之DL CC。DL CC A至C可被稱作服務CC、服務載波、服務單元，等等。如若CIF去能，則每一DL CC僅能夠根據LTE PDCCH規則而在無CIF之情況下發射PDCCH，PDCCH對每一DL CC進行排程。另一方面，如若藉由(特定於UE群組或特定於單元之)上層傳訊而賦能CIF，則DL CC A(監測DL CC)可以能夠藉由使用CIF發射PDCCH以及 DL CC A之PDSCH，該PDCCH對不同的DL CC之PDSCH進行排程。在此情況下，PDCCH並非在DL CC B及DL CC C上發射，該等DL CC未經配置為PDCCH監測之DL CC。因此，DL CC A(監測DL CC)應包括所有以下三者：與DL CC A相關之PDCCH搜尋空間、與DL CC B相關之PDCCH搜尋空間，及與DL CC C相關之PDCCH搜尋空間。在本說明書中，假定PDCCH搜尋空間是根據載波定義的。 Figure 12 is a diagram of an example of scheduling in the case where a plurality of carriers are aggregated with each other. It is assumed that 3 DL CCs are aggregated, and DL CC A is configured as a DL CC for PDCCH monitoring. DL CCs A through C may be referred to as service CCs, service carriers, service units, and the like. If the CIF is de-energized, each DL CC can only transmit the PDCCH without CIF according to the LTE PDCCH rule, and the PDCCH schedules each DL CC. On the other hand, if CIF is enabled by upper layer communication (specific to UE group or cell-specific), DL CC A (Monitoring DL CC) may be able to transmit PDCCH by using CIF and PDSCH of DL CC A, the PDCCH schedules PDSCHs of different DL CCs. In this case, the PDCCH is not transmitted on DL CC B and DL CC C, which are not configured as DL CCs for PDCCH monitoring. Therefore, DL CC A (Monitoring DL CC) should include all three: PDCCH search space associated with DL CC A, PDCCH search space associated with DL CC B, and PDCCH search space associated with DL CC C. In this specification, it is assumed that the PDCCH search space is defined according to a carrier.

如前述描述中所提及，LTE-A假定在PDCCH中使用CIF以執行交叉CC排程。是否使用CIF(亦即，是否支***叉CC排程模式或非交叉CC排程模式)及模式之間的切換可經由RRC傳訊而以半靜態方式/特定於UE之方式得以配置。在進行RRC傳訊過程之後，使用者裝備可辨識CIF是否用於針對使用者裝備而待排程之PDCCH中。 As mentioned in the foregoing description, LTE-A assumes that CIF is used in the PDCCH to perform cross CC scheduling. Whether to use CIF (that is, whether to support cross-CC scheduling mode or non-cross-CC scheduling mode) and switching between modes can be configured in a semi-static manner/UE-specific manner via RRC communication. After the RRC communication process, the user equipment can identify whether the CIF is used in the PDCCH to be scheduled for the user equipment.

第13圖是由EPDCCH排程之PDSCH及EPDCCH的實例之圖表。 Figure 13 is a diagram of an example of PDSCH and EPDCCH scheduled by EPDCCH.

參看第13圖，一般而言，EPDCCH可以定義在PDSCH區域中發射資料之一部分之方式使用，且UE應執行盲解碼以偵測UE是否偵測到UE之EPDCCH。儘管EPDCCH執行與舊有PDCCH之排程操作相同之排程操作(亦即PDSCH、PUSCH控制)，但如若存取諸如RRH之節點的UE數目增大，則更大數目之EPDCCH被分配至PDSCH區域，且由UE執行之盲解碼之計數增大。因此，可能存在複雜度會增大之缺點。 Referring to FIG. 13, in general, the EPDCCH may be defined in a manner of transmitting a portion of the data in the PDSCH region, and the UE shall perform blind decoding to detect whether the UE detects the EPDCCH of the UE. Although the EPDCCH performs the same scheduling operation as the scheduling operation of the legacy PDCCH (ie, PDSCH, PUSCH control), if the number of UEs accessing a node such as the RRH increases, a larger number of EPDCCHs are allocated to the PDSCH region. And the count of blind decoding performed by the UE increases. Therefore, there may be a disadvantage that the complexity may increase.

第14圖是在TDD系統環境中將舊有子訊框分為一組靜態子訊框及一組撓性子訊框的實例之圖表。經由第8圖中之系統資訊區塊(system information block；SIB)配置之舊有上行鏈路-下行鏈路配置經假定為上行鏈路-下行鏈路配置#1(亦即DSUUDDSUUD)。假定基地 台經由預定信號將無線電資源之用途的重新配置資訊通知使用者裝備。 Figure 14 is a diagram of an example of dividing a legacy sub-frame into a set of static sub-frames and a set of flexible sub-frames in a TDD system environment. The legacy uplink-downlink configuration configured via the system information block (SIB) in Figure 8 is assumed to be uplink-downlink configuration #1 (i.e., DSUUDDSUUD). Assumed base The station notifies the user equipment of the reconfiguration information of the use of the radio resource via a predetermined signal.

無線電資源用途改變訊息(重新配置訊息)根據一預定規則而用於實現告知無線電資源之用途的目的，該等無線電資源：i)在接收重新配置訊息之時序(包括接收重新配置訊息之時序)之後出現；ii)在接收重新配置訊息之時序(不包括接收重新配置訊息之時序)之後出現；或iii)在自接收重新配置訊息之時序起經過預定時間(亦即子訊框偏移)之後出現。 The radio resource usage change message (reconfiguration message) is used for the purpose of informing the use of the radio resource according to a predetermined rule: i) after receiving the timing of the reconfiguration message (including the timing of receiving the reconfiguration message) Appears; ii) occurs after the timing of receiving the reconfiguration message (excluding the timing of receiving the reconfiguration message); or iii) after a predetermined time (ie, subframe offset) has elapsed since the timing of receiving the reconfiguration message .

基於前述描述中提及之內容，本發明說明在上行鏈路資料通道上執行揹負(piggyback on uplink data channel；PUSCH)之方法，或在根據負載狀態而變更特定單元(亦即，增強干擾管理及訊務調適(enhanced interference management and traffic adaptation；eIMTA)單元)中之無線電資源用途之情況下，在PUSCH上有效發射上行鏈路控制資訊(uplink control information；UCI)之方法。 Based on the content mentioned in the foregoing description, the present invention describes a method of performing a piggyback on uplink data channel (PUSCH) on an uplink data channel, or changing a specific unit according to a load status (ie, enhancing interference management and In the case of radio resource usage in the enhanced interference management and traffic adaptation (eIMTA) unit, a method of effectively transmitting uplink control information (UCI) on the PUSCH.

根據本發明，用途改變訊息(重新配置訊息)可在預定單元中以上層信號(例如SIB/PBCH/MAC/RRC)之方式或實體層信號(例如PDCCH/EPDCCH/PDSCH)之形式發射。此外，用途改變訊息可具有特定於UE、特定於單元、特定於UE群組或共用於UE群組之特徵。 另外，用途改變訊息可經由特定於UE之搜尋空間(UE-specific search space；USS)或共用搜尋空間(common search space；CSS)而在預定單元(例如PCell)中發射。 According to the present invention, the usage change message (reconfiguration message) may be transmitted in the form of an upper layer signal (e.g., SIB/PBCH/MAC/RRC) or a physical layer signal (e.g., PDCCH/EPDCCH/PDSCH) in a predetermined unit. Further, the usage change message may have UE-specific, cell-specific, UE-specific, or common UE group characteristics. In addition, the usage change message may be transmitted in a predetermined unit (eg, PCell) via a UE-specific search space (USS) or a common search space (CSS).

在以下描述中，為明確性起見，本發明基於3GPP LTE系統進行說明。然而，本發明所應用至之系統範圍可擴大至除3GPP LTE系統以外之不同系統。此外，本發明之實施例可擴展至以下情況：i)藉由載波聚合(carrier aggregation；CA)技術使用TDD單元，及至少一或更 多個聚合單元(亦即聚合單元之一部分或全部)在無線電資源用途改變模式下操作；及/或ii)藉由載波聚合(carrier aggregation；CA)技術使用TDD單元與FDD單元之組合(例如TDD PCell與FDD SCell之組合或FDD PCell與TDD SCell之組合)及至少一或更多個聚合單元(亦即聚合單元之一部分或全部)在無線電資源用途改變模式下操作。 In the following description, for the sake of clarity, the present invention is described based on a 3GPP LTE system. However, the system to which the present invention is applied can be extended to different systems than the 3GPP LTE system. Furthermore, embodiments of the present invention can be extended to: i) use a TDD unit by carrier aggregation (CA) technology, and at least one or more Multiple aggregation units (ie, part or all of the aggregation units) operate in a radio resource usage change mode; and/or ii) use a combination of TDD units and FDD units by carrier aggregation (CA) techniques (eg, TDD) The combination of PCell and FDD SCell or the combination of FDD PCell and TDD SCell) and at least one or more of the aggregation units (ie, part or all of the aggregation unit) operate in a radio resource usage change mode.

首先，根據舊有無線通訊系統(3GPP TS 36.213)，能夠確保上行鏈路資料通道(uplink data channel；PUSCH)上之上行鏈路控制資訊(unlink control information；UCI)揹負或在PUSCH上發射之上行鏈路控制資訊將經由基於上層信號(RRC)之額外MCS偏移配置(參看3GPP TS 36.213 8.6.3)而更可靠地發射。在此情況下，基於上層信號之額外MCS偏移經設定至經由揹負而在PUSCH上發射之UCI，該偏移經配置以確保UCI將被可靠地接收。特定而言，當服務單元接收上行鏈路信號(自使用者裝備發射)時，前述操作在以下情況下可十分實用：i)接收來自相鄰單元之強干擾，該相鄰單元在相鄰頻帶/通道上執行上行鏈路/下行鏈路通訊；或ii)接收來自相鄰單元之強干擾，該相鄰單元在相同頻帶/通道上執行上行鏈路/下行鏈路通訊。 First, according to the old wireless communication system (3GPP TS 36.213), it is possible to ensure that uplink control information (UCI) on the uplink data channel (PUSCH) is piggybacked or uplinked on the PUSCH. The link control information will be transmitted more reliably via an additional MCS offset configuration based on the upper layer signal (RRC) (see 3GPP TS 36.213 8.6.3). In this case, the additional MCS offset based on the upper layer signal is set to the UCI transmitted on the PUSCH via piggyback, the offset being configured to ensure that the UCI will be reliably received. In particular, when the serving unit receives an uplink signal (transmitted from a user equipment), the foregoing operations can be very useful in the following situations: i) receiving strong interference from neighboring units in adjacent frequency bands Perform uplink/downlink communication on the channel; or ii) receive strong interference from neighboring cells that perform uplink/downlink communication on the same frequency band/channel.

然而，如若相鄰單元在無線電資源用途之動態改變模式(亦即『eIMTA模式』)下操作，則就服務單元(例如賦能eIMTA之服務單元或去能eIMTA之服務單元)而言，儘管子訊框同等地用於上行鏈路之目的，但來自外部的干擾強度或干擾之改變程度可能根據每一子訊框而有所不同。 However, if the neighboring unit operates under the dynamic change mode of the radio resource usage (ie, the "eIMTA mode"), then the service unit (for example, the service unit that enables eIMTA or the service unit that can be eIMTA), although The frame is equally used for the purpose of the uplink, but the degree of change in interference intensity or interference from the outside may vary according to each subframe.

如具體實例，就服務單元而言，來自相鄰單元之由DL通訊(DL干擾)引起之干擾在用於上行鏈路用途之子訊框#A中被接收。就服務單元而言，來自相鄰單元之由UL通訊(UL干擾)引起之干擾在用於上行鏈路用途之子訊框#B中被接收。因此，就服務單元而言，根據用於UL用途之子訊框(組)，在慮及彼此不同之干擾特性的情況下，引入對獨立功率控制參數進行配置(例如根據子訊框(組)配置開放迴路參數(例如P_O、α)(及/或根據子訊框(組)獨立執行TPC積聚))之「依據子訊框(組)之UL功率控制」技術。 As a specific example, in the case of a serving unit, interference caused by DL communication (DL interference) from neighboring units is received in subframe #A for uplink use. In the case of a service unit, interference caused by UL communication (UL interference) from neighboring units is received in subframe #B for uplink use. Therefore, in terms of the service unit, according to the subframes (groups) for UL use, the independent power control parameters are introduced in consideration of different interference characteristics (for example, according to the subframe configuration) Open loop parameters (eg, P _O , α) (and/or independent implementation of TPC accumulation based on subframes (groups))) "Using sub-frame (group) UL power control" technique.

然而，儘管PUSCH(及/或在PUSCH上經由揹負而發射之UCI)發射功率經由接收強干擾(例如DL干擾)之UL子訊框(組) 中依據子訊框(組)之UL功率控制而經設定為較高值，但該發射功率不能確保在PUSCH上經由揹負而發射之UCI之成功接收。而且，就系統實施(或系統管理)而言，根據具有彼此不同之干擾特性之UL子訊框組，並非必須配置相同目標的目標區塊錯誤率(target block error rate；BLER)(以用於PUSCH的接收或在PUSCH上經由揹負而發射之UCI的接收)。因此，如以下表4中所示，根據具有彼此不同之干擾特性之UL子訊框組，獨立於彼此(例如彼此不同)之MCS偏移可經設定至在PUSCH上經由揹負而發射之UCI(亦即RI、CQI)。 However, although the PUSCH (and/or the UCI transmitted on the PUSCH via piggyback) transmits power via the UL subframe (group) that receives strong interference (eg, DL interference) The middle value is set to a higher value according to the UL power control of the subframe (group), but the transmission power cannot ensure successful reception of the UCI transmitted on the PUSCH via piggyback. Moreover, in terms of system implementation (or system management), it is not necessary to configure a target block error rate (BLER) of the same target according to UL subframe groups having mutually different interference characteristics (for Reception of PUSCH or reception of UCI transmitted on the PUSCH via piggyback). Therefore, as shown in Table 4 below, according to the UL subframe group having interference characteristics different from each other, the MCS offsets that are independent of each other (for example, different from each other) can be set to the UCI transmitted on the PUSCH via piggyback ( That is RI, CQI).

在下文中，本發明不僅提出賦能與CSI相關之UCI(亦即RI、CQI)的方法(該UCI根據具有彼此不同之干擾特性的UL子訊框組，在PUSCH上經由揹負而發射)以使MCS偏移配置彼此獨立(例如彼此不同)，而且提出賦能HARQ-ACK資訊之方法以應用彼此獨立(例如彼此不同)之MCS偏移配置(亦即)。 In the following, the present invention not only proposes a method of enabling UCI (i.e., RI, CQI) related to CSI (the UCI is transmitted on the PUSCH via piggyback according to a UL subframe group having interference characteristics different from each other). The MCS offset configurations are independent of each other (eg, different from each other), and a method of enabling HARQ-ACK information is proposed to apply MCS offset configurations that are independent of each other (eg, different from each other) (ie, ).

特定而言，在應用載波聚合技術(carrier aggregation；CA)之以下環境中，根據表5推導出與SCell(例如賦能eIMTA之SCell)相關之DL參考UL/DL配置之時，本發明十分實用。換言之，此情況之原因在於i)最終應用於SCell(例如賦能eIMTA之SCell)之DL參考UL/DL配置不能確保在設定至SCell的eIMTA(或配置有RRC的)DL HARQ參考配置之UL子訊框(亦即靜態UL SF)中之HARQ-ACK發射(亦即在PUSCH上經由揹負發射之HARQ-ACK)；或ii)最終應 用於SCell之DL參考UL/DL配置不能確保在接收相對較低干擾之UL子訊框組中之HARQ-ACK發射(亦即在PUSCH上經由揹負發射之HARQ-ACK)(參看3GPP TS 36.213)。 In particular, the present invention is very practical when deriving a DL reference UL/DL configuration associated with an SCell (eg, an SCell enabling eIMTA) according to Table 5 in an environment where carrier aggregation (CA) is applied. . In other words, the reason for this is that i) the DL reference UL/DL configuration that is finally applied to the SCell (eg, the SCell that enables eIMTA) cannot ensure the UL sub-configuration in the DL HARQ reference configuration of the eIMTA (or RRC configured) to the SCell. HARQ-ACK transmission in a frame (ie, static UL SF) (ie, HARQ-ACK transmitted via piggyback on PUSCH); or ii) final should The DL reference UL/DL configuration for SCell does not guarantee HARQ-ACK transmission in a UL subframe group that receives relatively low interference (ie, HARQ-ACK via piggyback transmission on PUSCH) (see 3GPP TS 36.213) .

在此情況下，例如，在前述表5(亦即，基於Rel-10/11 CA操作來推導SCell(服務單元)之DL參考UL/DL配置的方法)中，PCell可能始終假定將SIB1 UL-DL配置設定至PCell以作為DL參考UL/DL配置，無論採用自排程還是交叉載波排程(cross carrier scheduling；CCS)。 In this case, for example, in the aforementioned Table 5 (that is, the method of deriving the DL reference UL/DL configuration of the SCell (Service Unit) based on the Rel-10/11 CA operation), the PCell may always assume that the SIB1 UL- The DL configuration is set to the PCell as a DL reference UL/DL configuration, whether self-scheduled or cross carrier scheduling (CCS) is employed.

特定而言，如不確保前述之可靠的HARQ-ACK發射的實例，假定藉由使用載波聚合技術將兩個單元(亦即，非eIMTA PCell及賦能eIMTA之SCell)設定至未設定有PUCCH/PUSCH同時發射之UE(eIMTA UE)，則非eIMTA PCell之SIB1 UL-DL配置對應於UL-DL配置1，賦能eIMTA之SCell的SIB1 UL-DL配置對應於UL-DL配置1，且賦能eIMTA之SCell之eIMTA(或配置有RRC的)DL HARQ參考配置對應於UL-DL配置5。在此情況下，就賦能eIMTA之SCell 而言，假定固定的UL SF(亦即假定在接收到來自外部之相對較低干擾時的位置)對應於UL SF #2及撓性UL SF(亦即假定在接收到來自外部之相對較高干擾時的位置)對應於UL SF #3、#7及#8。此外，如若交叉載波排程(cross carrier scheduling；CCS)經設定至兩個單元，則賦能eIMTA之SCell的最終DL參考UL/DL配置由UL-DL配置1來決定。然而，在此情況下，由於賦能eIMTA之SCell的eIMTA(或配置有RRC之)DL HARQ參考配置(亦即UL-DL配置5)與初始DL參考UL/DL配置(亦即UL-DL配置1)彼此不同，因此就賦能eIMTA之SCell而言，可在PUSCH(亦即在SCell中發射之PUSCH)上在假定為撓性UL SF之位置處經由揹負而發射。 In particular, if the aforementioned example of reliable HARQ-ACK transmission is not ensured, it is assumed that two units (ie, non-eIMTA PCell and SCell of the enabled eIMTA) are set to not set PUCCH/ by using carrier aggregation technology. For a PUSCH simultaneous UE (eIMTA UE), the SIB1 UL-DL configuration of the non-eIMTA PCell corresponds to the UL-DL configuration 1, and the SIB1 UL-DL configuration of the SCell that enables the eIMTA corresponds to the UL-DL configuration 1, and is enabled. The eIMTA (or RRC configured) DL HARQ reference configuration of the SCell of the eIMTA corresponds to the UL-DL configuration 5. In this case, the SCell of eIMTA is enabled. In this case, it is assumed that a fixed UL SF (that is, a position assumed to be relatively low-interference from the outside) corresponds to UL SF #2 and flexible UL SF (that is, a relatively high reception from the outside is assumed The position at the time of interference corresponds to UL SF #3, #7, and #8. Furthermore, if the cross carrier scheduling (CCS) is set to two units, the final DL reference UL/DL configuration of the SCell that enables the eIMTA is determined by the UL-DL configuration 1. However, in this case, the eIMTA (or RRC configured) DL HARQ reference configuration (ie, UL-DL configuration 5) and the initial DL reference UL/DL configuration (ie, UL-DL configuration) of the SCell enabling the eIMTA 1) Different from each other, so in the case of the SCell enabling the eIMTA, it can be transmitted via piggyback at the position assumed to be the flexible UL SF on the PUSCH (i.e., the PUSCH transmitted in the SCell).

具體而言，如若賦能eIMTA之SCell之實際UL-DL配置(亦即經由重新配置DCI而經(重新)配置之UL-DL配置)係由UL-DL配置2配置，則就賦能eIMTA之SCell而言，(與DL SF #0、#1、#3及#9有關之)HARQ-ACK可在PUSCH(亦即在SCell上發射之PUSCH)上於假定為撓性UL SF之UL SF #7中經由揹負發射。 Specifically, if the actual UL-DL configuration of the SCell that enables the eIMTA (ie, the (re)configured UL-DL configuration via reconfiguration DCI) is configured by the UL-DL configuration 2, then the eIMTA is enabled. For SCell, the HARQ-ACK (related to DL SF #0, #1, #3, and #9) can be on the PUSCH (that is, the PUSCH transmitted on the SCell) on the UL SF that is assumed to be a flexible UL SF # 7 is transmitted via piggyback.

因此，如本發明之一個實施例，如若與依據子訊框(組)之UL功率控制相關的兩個子訊框組(亦即UL PC SF SET #0(接收相對較低干擾(例如UL干擾)的子訊框組)及UL PC SF SET #1(接收相對較高干擾(例如DL干擾)的子訊框組))經設定至特定單元(例如賦能eIMTA之單元)，則該單元(或基地台)可經由預定信號(例如上層信號(RRC))將用於UL PC SF SET #0之及用於UL SF SET #1之分別通知UE(例如eIMTA UE)。在此情況下，可由與相比相對較高之值配置。 Therefore, as one embodiment of the present invention, if there are two sub-frame groups associated with UL power control according to the subframe (group) (ie, UL PC SF SET #0 (receive relatively low interference (eg, UL interference) (sub-frame group) and UL PC SF SET #1 (sub-frame group receiving relatively high interference (such as DL interference))) (A sub-frame group receiving relatively high interference (such as DL interference)) is set to a specific unit (for example, a unit that enables eIMTA), then the unit ( Or base station) may be used for UL PC SF SET #0 via a predetermined signal (eg, upper layer signal (RRC)) And for UL SF SET #1 The UE (for example, eIMTA UE) is separately notified. In this situation, Can be Compared to a relatively high value configuration.

如一不同實施例，i)如若對應通訊單元之與依據子訊框(組) 之UL功率控制相關的子訊框組數目從一個改變至兩個；或ii)如若依據子訊框(組)之UL功率控制並非在對應通訊單元上配置，且依據子訊框(組)之UL功率控制經(重新)配置(賦能)，則可經配置以按照原樣重新使用/繼承先前已使用(或配置)之值(例如偏移)(例如用於UL PC SF SET #1之MCS偏移值可僅經傳訊)。 As a different embodiment, i) if the number of subframe groups associated with the UL power control according to the subframe (group) of the corresponding communication unit is changed from one to two; or ii) according to the subframe (group) The UL power control is not configured on the corresponding communication unit, and is (re)configured (energized) according to the UL power control of the subframe (group). Can be configured to reuse/inherit the previously used (or configured) values as they are (for example Offset) (eg MCS offset value for UL PC SF SET #1 may only be transmitted).

此外，i)如若對應通訊單元之與依據子訊框(組)之UL功率控制相關的子訊框組數目從一個改變至兩個；或ii)如若依據子訊框(組)之UL功率控制在對應通訊單元上配置，及依據子訊框(組)之UL功率控制未經配置(去能)，則經配置以用於特定UL功率控制子訊框組(UL power control subframe set；UL PC SF SET)之MCS偏移值，或應用於/用於特定UL功率控制子訊框組之MCS偏移值(例如經配置以用於UL PC SF SET #0之MCS偏移值(亦即))可經配置以按照原樣重新使用/繼承(亦即並非必須額外傳訊MCS偏移值)。 In addition, i) if the number of subframe groups associated with the UL power control according to the subframe (group) of the corresponding communication unit is changed from one to two; or ii) if the UL power control according to the subframe (group) Configured on the corresponding communication unit and unconfigured (de-energized) according to the UL power control of the subframe (group), configured for a specific UL power control subframe set (UL PC) MCS offset value of SF SET), or MCS offset value applied to/for a particular UL power control subframe group (eg, MCS offset value configured for UL PC SF SET #0 (ie, )) can be configured to reuse/inherit as it is (ie, it is not necessary to additionally communicate MCS offset values).
